B26b 11/00 U.S. Cl. 7-14.1 1 ClaimABSTRACT OF THE DISCLOSURE A multipurpose scraping tool having amagnetic device secured thereto for removably attaching said tool to anymagnetizable surface. The tool is especially useful to a housepainter inpreparing a wall preliminary to painting, said tool comprising a handle,hammering means at one end, a sharpened edge for scraping at the otherend, nailpulling means located therebetween, and a magnetic devicesecured to the tool.

This invention relates to a multipurpose tool having a magnetic devicesecured to said tool for attaching said tool to any magnetizable surfacewhere it is easily located and removed, and more particularly, thisinvention relates to a multipurpose scraping tool especially useful to ahousepainter, combining novel features within its structure to permituse as a scraper, a glazing tool, a nail puller, putty knife, and ahammer.

A housepainter, or one performing similar tasks, ordinarily must carry amultitude of separate tools, each having one or two functions, in orderto perform operations which are preliminary to the painting operation.Frequently, these tools are misplaced, or fall from the ladder to thelloor below, thereby resulting in damage to the tool, or injury topersons. The instant invention rectilies these difficulties by providinga single tool having a multitude of uses, such as a paint scraper,hammer, nail puller, glazing tool, putty knife, all of which areincorporated 'within the tool structure, and including means formagnetically attaching the tool to any magnetizable surface nearby, suchas a steel ladder, or scaffold, where it is retained for future use.

It is, therefore, an object of this invention to provide a multipurposescraping tool which is efficient in design, simple to use, andeconomical to manufacture.

Another object of this invention is to provide a multipurpose scrapingtool having a handle, a hammerhead at one end of said tool, a sharpenededge useful for scraping, glazing, or puttying, at the other end,nailpulling means located therebetween, and a magnetic device secured tothe tool for attaching the tool to any nearby magnetizable surface,

Another object of the invention is to provide a multipurpose scrapingtool having a handle with a built-in magnetic device.

Other objects and advantages of this invention will be made readilyapparent from the disclosure in the attached specication, and from theaccompanying drawing, wherein:

FIG. 1 is an elevational rear view of a specic embodiment of themultipurpose scraping tool comprising the subject matter of the instantinvention.

FIG. 2 is a sectional view taken substantially on line 2-2 of FIG. l,showing the various components of the magnetic device.

FIG. 3 is a partial elevational front View of a specific embodiment ofthe instant invention showing the projected portions of the magneticdevice attached to the scraping tool.

Referring now to the drawing, wherein like numerals indicate likeelements throughout the several views, a

Ffice specific embodiment is generally indicated by the numeral 10. Asshown in FIG. 2, the multipurpose tool, or paint scraper `10, includesblade member 12, preferably of onepiece steel construction, said blademember 12 having an upper portion 14, an intermediate portion 16, and alower portion 1S, all of which are integrally connected so as to formthe basic tool structure.

Upper blade portion 14 is a solid cylinder of considerable weightrelative to the remainder of blade 12, having flattened front and rearsurfaces 15, 17 which are parallel to the flattened intermediate portion16, Edges 19, 21, chamfered at approximately 45 are provided oncylindrical surfaces 15, 17, respectively. As is readily apparent,either surface 15 or surface 17 may be used as a hammer for drivingnails, tacks, etc., into a wall.

Intermediate blade portion 16 extends forwardly from said upper portion14 and is relatively flat, having a substantially rectangularcross-section. A pair of holes 22, 24 spaced apart and located on thelongitudinal axis of intermediate portion 16 provide attaching means forhandle 30. Handle 30 comprises front and rear sections 32, 34, eachsection having a pair of holes 36, 38 spaced apart and located on thelongitudinal axis of said sections 32, 34, which are aligned with holes22, 24 so as to permit the fastening of sections 32, 34 to intermediateblade portion 16 with rivets 39. In lieu of rivets 39 other mechanicalfasteners, such as pins, screws, or chemical adhesives, such as epoxyresins, may be substituted therefor.

Sections 32, 34 may be made of non-metallic materials, such as plastics,wood, rubber, or non-magnetizable metals, such as aluminum, glass, ormagnetizable materials which are magnetically insulated from themagnetic device placed nearby. Sections 32, 34 have flat parallelexternal and internal surfaces `40, 42, 44, 46, and said externalsurfaces 40, 44 may be marked, or scored, in any fashion desired toprovide additional gripping surface. Sections 32, 34 have approximatelyuniform thicknesses throughout their length having sides 48 which taperdownwardly from the wider upper end 50 to the narrower lower end 52.Edge 54 of handle sections 32, 34 is contoured in a concave manner so asto partially envelop the cylindrical upper blade portion 14, or hammer,to which edge 54 is adjacently placed.

In this manner a reduced-width handle 30 which is easy to grip, coversthe underlying intermediate blade portion 16 `where it is securedthereto.

A recess, or shaped cavity 6l) is provided in either one of saidsections 32 or 34, as shown in 32 in the drawing, said cavity [beingapproximately centrally disposed and extending forwardly from internalsurface 42 to form a rst zone 62 of rectangular dimensions and parallelwith surface 42, a second zone 64 also of rectangular shape andextending from zone 62 forwardly, but of reduced area, and a third zone66 partially extending from zone 64 and communicating with externalsurface 4t) by a pair of rectangular conduits to form apertures 68, 70on surface 40. Cavity 60 is dimensionally proportioned so as to receiveand support the magnetic device 72 which is placed therein.

The magnetic device 72 includes a permanent magnet 74 and a magneticallyadhering pole piece 76, said permanent -magnet 74 being a bar magnethaving a substantially flattened rectangular shape. Permanent magnet 74may be made of any material possessing sufficient magnetic strength tosupport scraping tool 10 when said tool is placed against an upstandingmagnetizable surface. Pole piece 76 is of generally U-shaped dimensions,preferably of steel construction, and has a flattened middle portion 78with perpendicular flange members or legs 80 projecting forwardly frommiddle portion 78 at its upper and lower ends. Flange members 80 have across-sectional rectangular shape of approximately the same size asaperture 68, 70. Flange members 80 are of sufficient length to projectbeyond surface 40 after permanent magnet 74 and pole piece 76 are placedwithin second zone 72 of cavity 60.

Middle portion 78 includes a front and rear surface 81, 82 which aredisposed parallel to intermediate blade portion 16 and is separatedtherefrom by a magnetically insulating member 84. Insulating member 84,which may be of a fibrous nature, is also of generally rectangulardimensions, is placed at against surface S2 and lls first zone 62 ofcavity 60. In this manner, the pole piece 76 and permanent magnet 74 areinsulated from intermediate blade portion 16, thereby preventing themagnetization of said blade portion.

Lower blade portion 18 includes a triangular aperture 92 beingapproximately centrally located along the longitudinal axis of portion18 wherein the apex of aperture 92 points downwardly. In order toprovide theleverage for removing nails, lower blade portion 18 is bentat a position above aperture 92 and said portion shown at position 22forms an angle of approximately 20 with the longitudinal axis, therebylextending in a direction away lfrom the surface upon which the tool isplaced.

In using the above-described scraping tool as a hammer, the operatorgrasps handle 30 and proceeds to apply the upper blade portion 14against the nail, or tack, by means of placing surfaces 15 or 17directly in contact with said nail. By reversing the position of thetool in the users hand, the user may then remove nails, or tacks, byinserting said nails, or tacks, through aperture 92 and by applying theproper leverage, remove' the nail, or tack, from the surface.

In a similar fashion the operator may use tool 10 to scrape paint,varnish, or any other coated surface capable of being removed by thesharpened edge 90. Putty may also be applied to cracks, holes, by thelower yblade portion 18.

Upon completion of any of the scraping, glazing, hammering, nailpulling, or puttying operations, the user can easily temporarily attachmultipurpose tool 10 to any nearby magnetizable surface merely byplacing magnetic device 72 of tool 10 against said surface whereby, byvirtue of the magnetic forces induced within said surface the tool isrmly held in place. The magnetizable surface requires no added holdersor additional magnetic devices 'to be eective. Once tool 10 is securedit remains out of the users way, but within easy reach for further use.This is especially important when working on elevated structures, suchas in new building construction, where the elimination4 of fallingobjects is especially noteworthy.

Thus, from the foregoing, it will be seen that the instant inventionprovides a multipurpose tool which is simple in design and manufacturehaving a magnetic device attached thereto for attachment and subsequentdetachment from any magnetizable surface.

While a preferred embodiment of the multipurpose scraping tool has beendescribed in the foregoing description, it should be understood thatthis invention is not limited in its scope to the embodiment described,and variations in the form of the invention are contemplated thereby.
